We frequently come across with scalar values like as length, mass, time, distance, speed, area, volume, temperature, work, money, voltage, density, resistance etc. In science, we also come across vector quantities like displacement, velocity, acceleration, force, weight, momentum, electric field intensity which have to be measured in different way. In this chapter we will discuss about the combination of these two concepts in Vector Algebra.
In the above figure, the first two represent direction, in the third, the definite section ‘ab’ represents a scalar value l and a direction. The combination of scalar value and a direction is called a vector
Types of Vectors
Free Vector : Vectors having fixed magnitude and fixed direction, which can move freely around the space are called Free Vectors. In this chapter, we will discuss about Free Vectors only.
